Lost Files

I have switched from using the old express to the new express on a school account and it asked if I wanted to use more storage that was available on my school account so I clicked yes, and now I do not have any access to all of my files and templates I created on the old version of Adobe Express. How to I gain access to these? Is there any hope of getting them back? Also, I no longer have calibri as a font option and all and cannot seem to add it...I have just switched every school document over to this font as our standard and now if I use Express, this will be miss matched. Thank you for your help
